I am using WeatherCustom widget, is there a way to convert temperature from Celsius to Fahrenheit, for example by using formula in Temperature ID. Something like
(ObjectID *9/5)+32

Apparently, this feature works only for widgets with HTML property. It will be great to clarify it in VIS Wiki

@ap2017 Install the Javascript Adapter and in Userdata.0 create a new Datapoint as Number.
The goto Javascript and create a new "Javascript".
Insert this and Edit for your needs:

on({id: 'accuweather.0.Current.Temperature'/* <<< This has to be your AccuWeather Temp. No matter which one*/, change: "ne"}, function (obj) {
  setState("0_userdata.0.New_Object"/*<<<This has to be your new Datapoint*/, (getState("accuweather.0.Current.Temperature"/*<<< This has to be the same AccuWeather Temp. as above*/).val * (9 / 5) + 32), true);
});

then goto VIS and select the Object created in Userdata.0

@CrunkFX Thank you. Can same be done by binding ObjectID in widget? Something like:
{objectID;*(9);/(5);+(32);} For some reason it does not work for me.

@ap2017 sagte in VIS formula in Object ID:

@CrunkFX Thank you. Can same be done by binding ObjectID in widget? Something like:
{objectID;*(9);/(5);+(32);} For some reason it does not work for me.

Yes you can just use bindings in vis for calculations.

“ You can use this pattern in any text, like

My calculations with {objectID1;operation1;operation2;...} are {objectID2;operation3;operation4;...}
or color calculations:

#{objectRed;/(100);*(255);HEX2}{objectGreen;HEX2}{objectBlue;HEX2}
“
